Its been too long for me to give much detail, I definitely wrote about this
multiple times, so check the archives.  This is not a great setup, but it is
necessary because pd sends drawing commands with pixel values to pd-gui.  But
I remember it was something like this:

* set [tk scaling 1] on all platforms
* measure the boxes a lot, on various platforms and versions
* fix when the pixel values are different

The real way to fix this is to make pd know as little as possible about the
GUI stuff, then things can be handled much better in pd-gui.  If you are going
to put work into this, the best approach is also a more incremental approach.
 This approach will also easily give Pd a scalable GUI.

* look for any sys_vgui() call in pd that sends raw Tcl
* convert this to a pd message one at a time
* push the logic to pd-gui as much as possible

For example, take src/g_vumeter.c.  The drawing should all happen in
Tcl/pd-gui.  Pd should just send the values to be drawn.  Same goes with
g_array.c.
